Brickearth
Brickearth is a term originally used to describe Superficial deposits, superficial windblown deposits found in southern England. The term has been employed in English-speaking regions to describe similar deposits. Brickearths are periglacial loess, a wind-blown dust deposited under extremely cold, dry, peri- or postglacial conditions. The name arises from its early use in making house bricks, its composition being suitable for brick-making without additional material being added; unlike clay, its bricks can be hardened (fused) at lower temperatures, including in wood-fired kilns. The brickearth is normally represented on 1:50,000 solid and drift edition geological maps. In the River Thames, Thames valley, in broad patches brickearth overlies fluvial terrace gravel; it has been reclassified on later maps as the "Langley, Slough, Langley Silt Complex". Description Brickearth is a superficial deposit of homogeneous loam or silt [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superficial Deposits
Superficial deposits (or surficial deposits) refer to geological deposits typically of Quaternary age (less than 2.6 million years old) for the Earth. These geologically recent unconsolidated sediments may include stream channel and floodplain deposits, beach sands, talus gravels and glacial drift and moraine. All pre-Quaternary deposits are referred to as bedrock. Types and history There are several types of superficial deposit, including raised beaches and brickearth. These were formed in periods of climate change during the ice ages. The raised beaches were generally formed during periods of higher sea level, when ice sheets were at a minimum, and the sand and shingle deposits can be seen in many low cliffs. The brickearth is originally a wind-blown dust deposited under extremely cold, dry conditions but much has been re-deposited by flood water and mixed with flints. Superficial deposits were originally recorded only onshore and around the coast where they were laid down b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Stock Brick
London stock brick is the type of handmade brick which was used for the majority of building work in London and South East England until the increase in the use of Flettons and other machine-made bricks in the early 20th century. Its distinctive yellow colour is due to the addition of chalk. Another important admixture is 'spanish', which is made up of ash and cinders from incinerated waste and rubbish. The spanish ignites on firing and reduces fuel costs at the firing stage. London Stocks are still made in comparatively small quantities in traditional brickworks, mainly in Kent and Sussex, for heritage work, and machine-made versions are available for use where a cheaper approximation to the traditional product is acceptable.Brunskill, R. W. ''Brick Building in Britain''. Victor Gollancz in association with Peter Crawley, 1997. Red stock bricks are also fairly common, but only the yellow or brown bricks are usually known as London stocks. History During the 19th century, ...

Loess
A loess (, ; from ) is a clastic rock, clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loesses or similar deposition (geology), deposits. A loess is a periglacial or aeolian processes, aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay with a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. Usually, they are homogeneity and heterogeneity, homogeneous and highly Porosity#Porosity in earth sciences and construction, porous and have vertical capillaries that permit the sediment to fracture and form vertical cliff, bluffs.

River Thames
The River Thames ( ), known alternatively in parts as the The Isis, River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the Longest rivers of the United Kingdom, second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west, it flows through Oxford (where it is sometimes called the Isis), Reading, Berkshire, Reading, Henley-on-Thames and Windsor, Berkshire, Windsor. The Thames also drains the whole of Greater London. The lower Reach (geography), reaches of the river are called the Tideway, derived from its long Tidal river, tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of . From Oxford to the estuary, the Thames drops by . Running through some of the drier parts of mainland Bri ...

River Medway
The River Medway is a river in South East England. It rises in the High Weald AONB, High Weald, West Sussex and flows through Tonbridge, Maidstone and the Medway conurbation in Kent, before emptying into the Thames Estuary near Sheerness, a total distance of . About of the river lies in East Sussex, with the remainder being in Kent. The Medway has a Drainage basin, catchment area of , the second largest in southern England after the River Thames, Thames. The map opposite shows only the major tributaries: a more detailed map shows the extensive network of smaller streams feeding into the main river. Those tributaries rise from points along the North Downs, the Weald and Ashdown Forest. Tributaries The major tributaries are: * River Eden, Kent, River Eden * River Bourne, Kent, River Bourne, known in the past as the Shode or Busty * River Teise, major sub-tributary River Bewl * River Beult * Loose Stream * River Len Minor tributaries include: * Wateringbury Stream * East Mal ...

River Stour, Kent
The River Stour (, rhymes with "hour") is a river in Kent, England that flows into the North Sea at Pegwell Bay. Above Plucks Gutter, where the Little Stour joins it, the river is normally known as the Great Stour. The upper section of the river, above its confluence with the East Stour at Ashford is sometimes known as the Upper Great Stour or West Stour. In the tidal lower reaches, the artificial Stonar Cut short cuts a large loop in the natural river. The Stour has Kent's second largest catchment area (the River Medway having the largest). The lower part of the river is tidal; its original mouth was on the Wantsum Channel, an important sea route in medieval times. The river has three major tributaries, and many minor ones. For much of its length, it flows in a generally south-west to north-east direction. The historic city of Canterbury is situated on the river, as are the former Cinque Port of Sandwich and the railway town of Ashford. The route of the Stour Valley Wa ...

Brickmaking
A brick is a type of construction material used to build walls, pavements and other elements in masonry construction. Properly, the term ''brick'' denotes a unit primarily composed of clay. But is now also used informally to denote building units made of other materials or other chemically cured construction blocks. Bricks can be joined using Mortar (masonry), mortar, adhesives or by interlocking. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region, and are produced in bulk quantities. Concrete masonry unit, ''Block'' is a similar term referring to a rectangular building unit composed of clay or concrete, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate. Fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since . Air-dried bricks, also known as mudbricks ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...

Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Otterham Quay
Upchurch is a village and civil parish in the Swale district of Kent, England. It is situated about north of the A2 road, between Rainham and Sittingbourne. History It is probable that, although today the land is low-lying and marshy, it was once higher than it is today. Upchurch lay on a pre-Roman trackway; the many linking roads are the result of Roman occupation, which had built a community of ex-soldiers who wanted to settle in England. A Roman cemetery has been discovered here. It is also the site of several Roman pottery works. A more recent pottery was established here in 1909 called the Upchurch Pottery. It became well known and could be found retailing through such outlets as Liberty & Co. It closed in 1963. The Upchurch Hoard is a hoard of well worn coins which date from the first and second century A.D. which were found close to Upchurch in 1950.

Hoo Peninsula
The Hoo Peninsula is a peninsula in Kent, England, separating the estuaries of the rivers Thames and Medway. It is dominated by a line of chalk, clay and sand hills, surrounded by an extensive area of marshland composed of alluvial silt. The name ''Hoo'' is a Saxon word believed to mean 'spur of land' or refers to the 'distinct heel-shape of the ridge of hills' through Hoo. Hoo features in the Domesday Book.''The Place Names of Kent'', Judith Glover, 1976, Batsford. The peninsula is home to internationally and nationally protected wildlife sites as well as industrial facilities and energy industries. History The Romans have been credited with the first two attempts at building a sea wall. The subsequent draining of the marshes created pastureland to support sheep. The area is rich in archaeology. Bronze Age implements and Jutish cemeteries have been found on the peninsula, and Roman pottery at Cooling. It was once the point of departure across the ancient Saxon fording ...
